Our effective tax rate for the first six months of 2013 decreased as compared with the first six months of 2012. This decrease is primarily due to a tax contingency recognized during the second quarter of 2012.

In our major tax jurisdictions, the earliest years remaining open to examination are as follows: US – 2008, Equatorial Guinea – 2008, Israel – 2008 and China –2010.
